4 Claims.

, This invention relates generally to adhesive medical bandages. Itpertains particularly to a type of adhesive bandage that serves not onlyas a protective covering for wounds, but also as a source of medicine. y

The invention represents an improvement over those bandages wherein themedicament is originally impregnated in a gauze pad. In the pres entinvention the medium of medication is not originally impregnated in agauze pad, but is contained in a small blister embedded in absorbentmaterial. When its use is desired the blister is gently pressed orsqueezed causing it to burst. The contents thereupon oozes out andimpregnates the absorbent gauze material. 7

There are many obvious advantages to a bandage of this kind. In theblister there is always contained a fresh supply ofmedicine. Themedicament is sealed within the blister. There'is no danger of itbecoming stale or drying out as would occur in those types of bandageswhere the medication is impregnated in the bandage for use at some laterdate.

The general object of this invention is a medical bandage containing areadily breakable blister in which there is contained a supply ofmedicament.

Another object of the invention is an adhesive medical bandagecontaining a ready source of medicine for topical application.

A further object of the invention is an adhesive bandage carrying afresh supply of medicine at all times, and which is particularlysuitable for use with boils, carbuncles, corns, and the like.

Another object of breakable blister serving as a source of medicine inthe treatment of sores, wounds, bruises, and the like.

These, as well as othe objects and advantages of this invention, will.become apparent as this specification unfolds in greater detail, and asit is read in conjunction with the accompanying drawings wherein apreferred form of the inven tion as well as several modifications areillustrated.

Fig. 9 is a cross section longitudinally through the center of a form ofthe invention similar to that form contained in Fig. '7 but with anadded feature contained in the blister; and

Figs. 10, 11, and 12 represent'further forms of the invention.

Referring to the drawings, particularly to Figs; 1 to 5, inclusive thereis disclosed an adhesive bandage containing a blister carrying a supplyof medicine. The bandage comprises a strip of adhesive cloth or tape l.The adhesive substance covers the inner or body contacting surface 2 ofthe strip. Adhering to the adhesive surface 2 is a substantially flatpad 3 consisting of a length of absorbent gauze material having severallayers of thickness. Pad 3 is secured to the adhesive strip in suchmanner that the free end l of the bottom layer as well as an extendedportion 5 of the top layer are in contact with the adhesive substance ofstrip l', as appears in Fig. 2. By securing the gauze in this manner tothe adhesive cloth there is no likelihood of the free ends 4 and 5 ofthe pad becoming loose and causing the pad. to unravel. Also, by rollingthe gauze material in a pad a series of folds or pockets are formedbetween the several layers of gauze. Between these folds, preferably thecenter'one, there is embedded a small, substantially flat blister 6carrying a fresh supply of medicine 1.

The medicine carrier is called a blister, as that term best describesits nature. It is intended to be a container 'of a medicinal substancewith a thin readily breakable skin covering 01' wall 8. Upon squeezingor the application of slight pressure, the substance within the blisteris intended to break through the tender wall of the blister andimpregnate the surrounding gauze material in which it is embedded.

The thin wall of the blister is intended to be of a soft tendermaterial. The blister is fashioned preferably of polyethylene plasticmaterial, which issoft and particularly adapted for the uses intended.The blister may, however, well be made of other materials suitable forthe purposes intended. The blister is substantially flat and,

of another form that the preferably contains a medicament, such asiodine, mercurochrome, or other antiseptic suitable for application witheveryday scratches, bruises and hurts. Blisters may be made up to carryother medicaments, such as, zinc oxide, petroleum jelly, sulfacompounds, and other ointments, salves, and powders.

An additional layer of gauze It may be laid longitudinally over the padwith its extended ends H secured in the adhesive substance of the tapeI. This will effectively confine the blister within the pad and preventits contents, when the blister is broken, from oozing out between thelayers of the gauze pad. If desired, the several layers of the gauze padmay be secured or other medicament. The blister is also preferably madeof polyethylene plastic material, or of some other material that issuitable for the use intended. Polyethylene is preferred because of itssoft, non irritating nature. In this form it is to be noted that theblister is in the nature of a container having a base 19 and a circularwall 29. The circular wall encompasses a core of medicament 2 I The coreis sealed in bya thin skin or wall 22. Because this form is ofparticular use for boils, carbuncles, and the like, the top surface 2-3of the blister is slightly concaved. Slight prestogether by one or morestitches through the pad.

The gauze pad as well as the adhesive portions of tape I extending outon either side of the pad are covered by a readily removable material,such as crinoline. This backing material serves as a protective. coverinand. faci itates ha dl of the bandage, particularly the adhesiveportions. This criholine material may be'a single strip runnin the fulllength or the bandag r. as h wn in Fig. Lit: may comprise, two strips52, one for each end of the bandage. Each strip I2 is adhered to the ahesive. side of the tape i and extends a little beyond the middle of thepad, so that both strips Will overlap each other on. the pad 3. The

overlapping portions of crinoline are free and mayv be readily liftedfor removal wh n h banda e is to be u ed as i l s rated in Fig. 1.

Having described theinven ion in il. its m ny advanta e now appear quitea p rent. I can'readily be seen how th se blisters m be made up to carrymedical substances of various t pesparticularly those tha are r q ired fr everyday use with bruises, cuts, burns, scratches, minor operations,etc,- The blisters may contain such Inedicainents as iodine,mercurochrome, Vaseline, z nc oxide, carbolie salve, icthyol, sulfa, andothers. The contents of the blister are sealed in and will remain freshat all times until ready for use without drying out, or becoming staleor contaminated. V

The bandage is particularly adaptable for emergency use. All one need dowhen using the bandage is to squeeze the blister slightly to allow it toburst and its contents to ooze out into the absorbent gauze pad. Thecrinoline is then removed and the bandage is applied to the affectedarea" of the body. Where the bandage is to be applied to the fingers,pressure exerted on the tape while applying Will be sufiicient to causethe blister to burst and emit its contents.

The invention m y ta many-for s. s m f Whi h re added here bel w.

The embodiment in Fig. 61s an econom cal Icrm adaptable forready usewith a. variety of medicine contained blisters. In; this form a blisterl3 containing a inedicam nti adhered to the e r f the adhesive side of astrip of tape 14. A pad of absorbent gauze is positioned over theblister and adhered to the tape. This is a quickly put together form,economical to manufacture, and provides fair results. this form tapes,blisters, and pads may be made-up separately for quick and readyassembly when needed. Crinoline backing may also be added to this formas in Fig. 1.

In Fig. 7 is disclosed another form of the invention that isparticularly adaptable for use with boils, carbuncles, and the like. Inthis form a strip of adhesive tape I! has adhered to its center ablister l8 containing a suitable boil ointment, r

sure on the circular wall will break the thin seal 22 and cause themedicament to ooze out. In this form the head of a boil where themedication is actually needed is permitted to extend into the core ofmedicament 2|. The circular wall and base of the blister are thickenedto maintain the form of the blister and to serve as a protective supportfor the boil against rubbing and irritation of clothing, The bliste maybe covered wi h a l yer oi gauze ut the p ly hyl ne. m t ial Of Which hbliste is c n tru e is .5 s h a so and non-irritating nature hat he guze pad can be dispensed with. The purpose of thisforrn of the inventionis primarily to keep the head of a boil lodged in the medication untilit is ripe? This form is also of value when used in the treat me t fcorns.

In cases f hose ells and ot e infec i us s res where it is desired thatthe wound be kept ope to prom te drainage, a form of the inv ntion asappears in F g- 9 ma be us d o a an ag Thi form is in all r spectssimilar o that o F g.- except that a small t mpon '24 t absorbent gauzeis con a ned in the core of the b iste e ulfed i a suita l ointment 2 Is form when the blister is squeezed the thin covering seal 26 breaks andaus s th tampon o pr trude s i ht y with the medicament. The blister isthen taped over he w nd. The ampon surround d by in ment will protrudeslightly into the open wound to effect a continued opening of the woundand to promote d ainag A. blister 21, such as illustrated in Fig. 10,con, taining a suitable medicament according to the use intended may beembedded in a sterile abs sorbent auze p 28 s r t d. in ig. 10. A padof. this nat r fin s many us s for topi a application as a dressing forminor operations, burn s res, and. o her ffli ti ns- There are otheruses in which the blister shown in Fig. 4 finds use, such as a swab ortampon, In Fig. 11 there is shown a swab stick 29 with a tip ofabsorbent gauze material at one end. A blister 30 containing a supply ofmedicament is embedded in the gauze tip -3 l- Sli ht ben in Q squeezingof tip 3| will break the blister and al low its contents to core out anda into h surrounding gauze.

In Fig. 12 there is shown a tampon 32 suitable for insertion into thecavities of th body, such as the nasal passages .and'the like. Containedwithin the tampon is a blister 33 of medicine, which also can be brokenb squeezing when its use is desired. The contents of the broken blistwill ooze out into the surrounding tampon material. Having described theinvention in its preferred form as well as in several other forms, it isin-. tended to claim all that may be reasonably included within thespirit and scope of the inven= tion as defined by the appended claims.
